Sambandið - A modern data platform for Iceland’s municipalities

Samband Íslenskra Sveitarfélaga is taking over the collection of municipal financial data. Together with Gangverk, they built a platform for collecting, validating, and sharing data that they can continue to expand for years to come.

Samband íslenskra sveitarfélaga

Sambandið sees the status of every submission in real time. Each municipality is marked delivered or outstanding, so follow-up is easy to coordinate.

Behind that overview, submissions flow through orchestrated pipelines with built-in data-quality checks. Hard rules that stop invalid data before it enters the platform, and softer checks that flag anomalies for review.
